Hello,
I'm tuning an NXP LDMOS FET model in Microwave Office. When my Vds current is about 20A at 12V, my output power on port 2 measured by the "PT" Total Power measurement shows ~100W (which is our optimization target).
Here is the part I don't understand: Why does PAE show about 75%? Shouldn't 100W/240W have a PAE of ~41%?
Port 1 (Pin) is 17dBm, so 0.050 Watts, a negligible amount.
(Pout-Pin)/Pdc == (100-0.050)/240W == 0.416.
What am I missing here?
Thanks for your help!
